Effects of Rhizobium Inoculant on Nodulation,Agronomic Traits and Yield of Different Soybean Varieties
摘要
Abstract
To clarify the effects of rhizobium inoculant application on the growth and yield of soybean varieties in the Qianxi-nan region of Guizhou Province,and to screen for efficient nitrogen-fixing soybean variety rhizobium combinations suitable for this area,four soybean varieties(Qiandou16,Qihuang34,Qihuang35 and Youchun1204)were used as test materials.A split-plot design was adopted to investigate the effects of rhizobium inoculation(A2)versus non-inoculation(A1)on nodula-tion,agronomic traits,growth period,and yield of soybean.The results showed that Youchun1204 exhibited the best nodula-tion response to rhizobium inoculation,with an increase in nodule number of 32.19％,while Qihuang34 showed the weakest response,with an increase of only 2.02％.Rhizobium inoculant primarily increased yield by significantly increasing the total pod number,effective pod number,and total seed number per plant,whereas it had no significant effect on seeds per pod or 100-seed weight.The yield of all four tested soybean varieties increased following rhizobium inoculation,with Youchun1204 and Qiandou16 showing significant yield increases of 9.52％and 8.61％,respectively.In conclusion,Youchun1204 exhibited the best compatibility with the tested rhizobium inoculant and can be recommended as a preferred combination for high-yield soybean cultivation in the Qianxinan region of Guizhou Province.关键词
